I would divide 15.26 by 4.36 then check it by multiplying 4.36 by the original answer
Well, to solve, garph the equation y=x^2+2x-8 and y=0
see where they intersect
anyway the easier way is to factor but anyway
0=(x-4)(x+2)
anyway
solution is x=4 and -2
A and D are answers (they are same)
This is the picture of the triangles.
triangle ABC. is rotated 180 degrees about point (0,0)
good luck
Answer:
r=-2.5
Step-by-step explanation:
collect like terms
0.25r+0.5r
0.75r-0.125=0.5+r
move terms
0.75r-r=0.5+0.125
collect the like terms
-0.25r=0.625
divide both sides by -0.25 to get your answer.
